Did you ever consider that your dusty Nintendo Switch, languishing in a drawer, might possess the processing might to revolutionize your 3D printing workflow? Probably not. But that’s precisely the kind of question one tinkerer, going by the handle Cocoanix 3D Printing, decided to answer, and the results are… frankly, astonishing.
This isn’t just about shaving off a few minutes here and there. We’re talking about a 90% speed increase. A standard 3DBenchy model, which previously took a laborious 90 minutes to materialize on a Prusa MK3S, now emerges from the nozzle in a mere 8 minutes and 41 seconds. That’s the kind of leap that forces you to re-evaluate what ‘aging hardware’ even means.
The secret sauce? Klipper firmware, a departure from the more traditional Marlin-based systems often found on older machines. Klipper’s architecture offloads the heavy lifting—the motion planning, the calculations, the complex dance of the printer’s axes—to a more powerful external computer. In this case, that powerful external computer is a jailbroken Nintendo Switch.
It’s a fascinating architectural shift. Instead of the printer’s onboard microcontroller — often an 8-bit workhorse struggling with modern demands — doing all the computational heavy lifting, Klipper effectively creates a distributed system. The Switch, with its quad-core ARM CPU (famously ARM Cortex-A57 cores, also found in some early smartphone flagships), becomes the brain, feeding instructions to the printer’s simpler motor drivers and hotend. This frees up the printer’s native hardware to focus on the physical execution, while the Switch handles the complex predictive modeling and control.
According to Cocoanix, this isn’t just about raw speed. The modder claims to have seen “less ringing and ghosting” in the prints, implying a tangible improvement in quality alongside the dramatic reduction in print times.
This is where the narrative gets particularly interesting. The Prusa MK3S, while a legendary machine, is a product of its time. Its onboard processor is a well-documented bottleneck for advanced features like Input Shaping, which is crucial for mitigating vibrations at higher speeds and accelerations. By offloading this processing to the Switch, Cocoanix is able to push the MK3S to what they describe as its “absolute speed limit: 400mm/s at 17,000mm/s² of acceleration.” For context, that’s warp speed for most consumer-grade printers.
Why Did Older Printers Benefit So Much?
The implication here is that many older, yet still capable, 3D printers are sitting on desks, performing adequately but well below their physical potential due to processing limitations. Adding a Raspberry Pi has been the go-to solution for years, offering a similar boost. But the Switch, with its integrated touchscreen and readily available ARM architecture, presents a surprisingly elegant—if unconventional—alternative. It’s a proof to the power of firmware flexibility and the often-overlooked processing capabilities of devices we’ve relegated to entertainment.
Is This the Future of 3D Printing Enhancement?
It’s unlikely to see a flood of manufacturers shipping printers with Switches tucked inside (though who knows with some of the more avant-garde designs out there). The real takeaway isn’t the specific console, but the architecture Klipper enables. For anyone with an older printer that feels sluggish, or one that simply can’t keep up with the demands of modern slicing software and advanced print settings, this hack shines a spotlight on a viable upgrade path. It’s a reminder that sometimes, the most innovative solutions come from repurposing the tech we already own.
Of course, the practicalities of setting this up aren’t trivial. The process involves flashing Ubuntu Linux onto the Switch, then installing and configuring Klipper. It’s a deep dive into the Linux command line and firmware configuration files. But for the dedicated enthusiast, the reward—dramatically faster, potentially higher-quality prints—is clearly worth the effort.
The resulting prints, while faster, do show some limitations, primarily the hotend and extruder becoming the new bottleneck. This is inevitable when you push a system so far beyond its original design parameters. But seeing a 3DBenchy printed in under nine minutes is a sight to behold, a clear demonstration of how much more performance can be wrung from older hardware with the right software and a bit of ingenuity.
This hack isn’t just about bragging rights; it’s about democratizing high-speed 3D printing. It shows that with a bit of technical know-how, you don’t necessarily need to drop thousands on the latest, fastest machine. Sometimes, all it takes is a jailbroken gaming console and some clever firmware.

Frequently Asked Questions
What is Klipper firmware?
Klipper is an open-source firmware for 3D printers that offloads complex motion calculations and other heavy processing tasks to a more powerful host computer, such as a Raspberry Pi or, in this case, a Nintendo Switch, while the printer’s onboard microcontroller handles basic motor control.
Will this work on any 3D printer?
Klipper is designed to be compatible with a wide range of 3D printer boards, but the specific setup and configuration will vary. Older printers with less powerful onboard processors tend to benefit the most.
Is my Nintendo Switch powerful enough for this?
Yes, the Switch’s quad-core ARM processor is significantly more powerful than the microcontrollers found on many older 3D printers, making it more than capable of handling the Klipper workload.
